The title compounds, C23H25Br2NO2 (1) and C31H29BrN2O4 (2), crystallize in the space group P21/n with two (1-A and 1-B) and one molecules, respectively, in the asymmetric unit of the cell. The molecular conformation of these compounds is stabilized by intramolecular C—H⋯O hydrogen bonds and C—H⋯N or C—H⋯π interactions. The crystal structure of 1 features a relatively strong Br⋯O=C halogen bond, which is not observed in the case of 2. Both crystal structures are characterized by the presence of C—H⋯Br hydrogen bonds and numerous intermolecular C—H⋯O hydrogen-bonding interactions.
